re 14594, the WHAM2 ISI config change attempt yesterday.  Attached are performance spectra from this moring at 3am, and at 8am this morning after I switched the ISI back to the same configuration before we started--that is with the X Y Z blends switched from 01-28 to 100mHz.

I'd say the differences are minor and no great improvement but the ground noise is also slightly higher at 8am.  Plus it would be a lot easier with overlay plots.

I'm pretty sure we've decide to actually run with all the HAM ISI dofs to be the 01_28 blends.  THe X Y Z dofs being in 100mz is a left over from when Sebastien was working on Sensor Correction.
